Looking at solutions to stop neighbouring cats using our borders as a toilet, there are several cats in the area that seem to use our garden as a party zone, not too bothered about the cats but would rather not have the shit.
Been looking at the above link as a solution but not sure if its cruel...? It says its not sharp enough to hurt them but enough to make it uncomfortable. If used it would just be on the ground level, so not an area where they would be jumping to etc without any warning. Or should i just avoid this sort of thing?
If avoid, then does anyone have any alternatives?
